Travel by Train

In addition to 10 historic and scenic railroads, Colorado offers modern and convenient train-travel options. Amtrak’s California Zephyr line makes the trip from Chicago, to Emeryville, California. On its way, it makes a stop in Denver and passes through Fort Morgan, Fraser, Granby, Glenwood Springs and Grand Junction. The Southwest Chief goes from Chicago to Los Angeles, with Colorado stops in Lamar, La Junta and Trinidad.

In 2016, the wildly popular “ski train” returned to ferry skiers and boarders from Denver’s Union Station right to the base area of Winter Park Resort on winter weekends. The Winter Park Express zips winter lovers straight to the slopes in just two hours.

Driving Distances

Colorado is the eighth-largest state in the US, measuring 380 miles east to west and 280 miles north to south. Luckily, with so much to see and do, the state is easy to navigate. Keep in mind when planning to travel from one region to another that there might be some mountains in between you need to go around — it's not always a straight shot from one point to another! Check out our drive-distance chart to get an idea of some common routes from corner to corner.

If you want to get in touch with knowledgeable locals during your visit, all you need to do is head to one of the nine Colorado Welcome Centers. There’s one located in each corner of the state and at both ends of the major interstates that bisect the state — I-25 and I-70. Stop by for personable, face-to-face travel advice, and take your pick from scores of maps, brochures and regional guides. The coffee is always hot, and each center has Internet access and clean restrooms, as well as information on weather and road conditions.
